Solution Overview
Problem
Current sports equipment with vibration plates lacks a combination of drive systems that enables a lighter design while achieving a broader range of vibrations, limiting the effectiveness of muscle stimulation.
Innovation Solution
The sports equipment incorporates a vibration plate with a support frame, an electric motor attached to the plate moving a seesaw via a V-belt, and a rotary motor with eccentric weights that rotate left and right, allowing for vibrations between 4 to 50 Hz, adjustable by user position and rotation direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a DC motor with push rod or eccentric wheel is used for rocking device, then vibrations range from 4 to 20 Hz can be generated, but the device becomes heavy and complex
Solution Approach 1:
The patent combines a rocking mechanism and a rotating mechanism into a single integrated system. The electric motor drives both the rocking motion (4-20 Hz) and the rotation (up to 30 Hz) simultaneously, allowing the device to achieve a broader vibration frequency range (4-50 Hz) without requiring separate heavy motor systems for each function.
Solution Approach 2:
The single electric motor in the patent serves multiple functions: it generates both the rocking vibration and the rotational vibration. This multi-functional design eliminates the need for separate specialized motors, thereby reducing overall device weight while maintaining versatility in vibration generation.
2Adaptability or versatility
If an AC motor is used for rotation device, then vibrations up to 30 Hz can be generated, but the motor becomes large and heavy (about 15 x 30 x 15 cm)
Solution Approach 1:
The patent merges the functions of separate rocking and rotating mechanisms into one integrated system driven by a single electric motor. This combination allows the device to achieve high vibration frequencies (up to 50 Hz) without requiring a large AC motor, as the motor operates optimally within its designed parameters while the mechanical design amplifies the vibration effects.
Solution Approach 2:
The patent changes the operational parameters of the motor by utilizing both rocking and rotating modes simultaneously. This allows the system to achieve a broader frequency range (4-50 Hz) than a single-mode motor could provide, effectively reducing the need for an oversized motor while maintaining high-frequency vibration capability.
3Adaptability or versatility
If separate rocking and rotating mechanisms are used, then comprehensive vibration coverage is achieved, but the device complexity increases
Solution Approach 1:
The patent combines multiple vibration-generating functions into a single integrated mechanism. The electric motor simultaneously produces rocking motion and rotational motion, which together create comprehensive vibration coverage (4-50 Hz). This merging approach maintains versatility while significantly simplifying the drive system compared to having separate independent mechanisms.
4Stability of the object's composition
If the seesaw has low weight for rocking device, then the device itself does not shake excessively, but the vibration amplitude decreases
Solution Approach 1:
The patent combines rocking and rotating mechanisms to generate vibrations through two different motion patterns simultaneously. This dual-mechanism approach ensures that even with a lightweight seesaw, sufficient vibration amplitude is achieved because the rotational component compensates for the reduced mass, while the integrated design maintains overall system stability.

AI summary
A new sports device (1) is described, comprising a vibration plate (4) for muscle stimulation, a support frame (3), a rocker formed by the vibration plate, and an electric motor (15) attached to the vibration plate, which moves the rocker up and down via a V-belt (16). Additionally, a rotary motor (20) with a drive shaft (33) and an eccentric weight mounted on the shaft is provided. The rotary motor (20) is designed to rotate clockwise and counterclockwise, and the eccentric weight is formed by a first eccentric weight part (40) mounted on the shaft and a second eccentric weight part (45) rotatable on the shaft. A stop (44) is provided on the first eccentric weight part (40), against which the second eccentric weight part (45) abuts during clockwise or counterclockwise rotation.
